At two points, the distance between which is 600 km, two trains left at the same time towards each other and met after 4 hours. Find the speed of 1 train if the speed of 2 trains is 65 km / h.

Let’s find the distance that the 2nd train traveled in 4 hours.
65 * 4 = 260 km.
The trains have met, so we will find the distance that the 1st train traveled in 4 hours.
600 – 260 = 340 km.
Let’s find the speed of the 1st train.
340/4 = 85 km / h.
Answer: 85 km / h is the speed of the first train.
